Pool sand filter system FSP-500 incl. sand

The Pool Sand Filter System FSP-500 comes with a base plate that holds the polypropylene filter tank equipped with a 6-way valve with a gauge and glued connection fitting of ø50 mm. On the same base plate, the circulation pump, which has a hair filter with a capacity of 9 m³/h, is also placed and connected to the filter tank through a flexible hose. The filter uses filter sand (recommended grain size of 0.6 - 1.2mm) to capture impurities from the pool water. The filter tank is filled with filter sand and serves as a dirt collector. When the valve is set to "Filter," the contaminated pool water is automatically sucked through a hose system and pushed into the control valve with a patented filter, and from there, it is transported to the upper part of the filter tank. The water is then pushed through the sand, which removes fine impurities, and discharged into the lower part of the tank. Through the control valve, the water is directed back into the pool through hoses. The entire process is continuous, automatic, and guarantees complete filtration of the pool water. After a certain period of operation (4-8 weeks), impurities will accumulate in the filter tank, leading to a decrease in water flow through the sand and a reduction in flow through the filter unit (indicated by an increase in pressure on the gauge). This means it's time to clean the filter. To do so, all you need to do is move the control lever of the 6-way valve to the "Rinse" position. This will automatically reverse the water flow, causing the water to flow from the bottom up through the filter sand, washing out the accumulated impurities and pushing them out through the drainage line. After the filter is rinsed, move the valve lever to the "Pre-Filter" position and turn on the pump for half to one minute. Then, move the valve lever back to the "Filter" position to resume normal filter operation.
